We're dividing 71412666 by 515 
We're looking to find how many times 515 goes into 71412666.

On to step 1:
If we divide 7 by 515, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 515

Advancing to step 2:
When dividing 71 by 515, we get 0 with a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Grab the next digit (4) from the dividend, add it to 71, then carry on: 714 / 515

Advancing to step 3:
The number 515 fits into 714 1 times, leaving a remainder of 199.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 515 from 714 and we're left with 199.
Grab the next digit (1) from the dividend, add it to 199, then carry on: 1991 / 515

On to step 4:
The number 515 fits into 1991 3 times, leaving a remainder of 446.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 1545 from 1991 to get 446.
Grab the next digit (2) from the dividend, add it to 446, then carry on: 4462 / 515

On to step 5:
4462 divided by 515 is 8 with a remainder of 342.
Use 8 as the next digit of our solution. 
Result so far: 138.0
Deduct 4120 from 4462 and we're left with 342.
Fetch the next digit (6) from the dividend, attach it to 342 and continue: 3426 / 515

On to step 6:
3426 divided by 515 is 6 with a remainder of 336.
Put 6 as the next digit of the answer. 
Result so far: 1386.0
If we subtract 3090 from 3426, we get 336.
Fetch the next digit (6) from the dividend, attach it to 336 and continue: 3366 / 515

Step 7:
When dividing 3366 by 515, we get 6 with a remainder of 276.
Write down 6 as next digit of the result. 
Result so far: 13866.0
If we take 3090 away from 3366, we end up with 276.
Include the next digit (6) from the dividend after 276, then repeat: 2766 / 515

Advancing to step 8:
The number 515 fits into 2766 5 times, leaving a remainder of 191.
The number 5 becomes the next digit in our result. 
Result so far: 138665.0
Subtracting 2575 from 2766 leaves us with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

On to step 9:
When dividing 1910 by 515, we get 3 with a remainder of 365.
The next digit of our result is 3. 
Result so far: 138665.3
Subtracting 1545 from 1910 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Moving on to step 10:
3650 divided by 515 is 7 with a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 138665.37
Deduct 3605 from 3650 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 11:
The number 515 fits into 450 0 times, leaving a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 138665.37
Subtracting 0 from 450 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 12:
515 can be fit into 4500 8 times, resulting in a remainder of 380.
Write down 8 as next digit of the result. 
Result so far: 138665.3708
If we subtract 4120 from 4500, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 13:
515 goes into 3800 7 times with a remainder of 195.
Record the quotient 7 as the next digit in the result. 
Result so far: 138665.37087
If we subtract 3605 from 3800, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 14:
515 goes into 1950 3 times with a remainder of 405.
Put 3 as the next digit of the answer. 
Result so far: 138665.370873
The remainder is 405 after subtracting 1545 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 15:
When dividing 4050 by 515, we get 7 with a remainder of 445.
Put 7 as the next digit of the answer. 
Result so far: 138665.3708737
The remainder is 445 after subtracting 3605 from 4050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Moving on to step 16:
4450 divided by 515 is 8 with a remainder of 330.
Put 8 as the next digit of the answer. 
Result so far: 138665.37087378
Deduct 4120 from 4450 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

The quotient of the division is 138665.37087378, and the remainder is 3.3e-07.
